JAMES V. WASHIBURNE, OF FULTON, NEW YORK.

SHADE-ROLLER.

- Application filed July 19, 1911, Serial No. 639,375.

To all whom it may concern:

Be it known that I, JAMES V. Wasn- BURNE, of Fulton, in the county ofOswego, in the State of New York, have invented new and usefulImprovements in Shade Rollers, of which the following, taken inconnection with the accompanying drawings, is a full, clear, and exactdescription.

This invention relates to certain improve. ments in shade rollers of theclass set forth; in. my pending application #543,229 filed February 11,1910 in which the roller is.

hollow throughout a portion of its length for receiving a centrallydisposed spindle having a spear at one end adapted to interlock with asuitable bracket for holding the spindle stationary during the operationof the roller by or against the action of a suitable retracting springwhich is coiled around the spindle and has one end secured.

thereto and its other end secured to a suitable disk on the end of theroller adjacent the spear.

The roller and spindle are usually made of cold rolled steel having areduced end provided with fins driven into one end of the spindle tolock the two elements together, the intermediate portion of the spearhaving a circular bearing upon which the catch carrying disk isjournaled and therefore the spear performs the quadruple func-; tions ofsupporting one end of the spindle,

holding said spindle stationary against rotation; forming a bearing forthe catch carrying plate for holding the roller concentric with thespindle and permitting it to. rotate, and also serving as a clutchsectionf cooperating with the catch plates to hold the:

when the spring is tensioned axially,'as, for example, when attaching itto the spindle I and to the disk, the central portion of the end helixof the spring within the channel or groove tends to rock toward thecatch plates to such an extent as to sometimes in-- terfere with theoperation of said plates, and the main object of my present invention isto obviate this difficulty. by forming. two substantiallyquadri-circular channels and leaving the intervening bridge betweentheir ends so that the adjacent arched portion of the helix will haveinnerand outer bearings and thereby be held against tiltingvm'ovementrelatively to the disk. l i

It is sometimes desirableto place the curtain roll at the bottom of thewindow frame to enable the curtain to beunrolled from the bottom upwardin -which case it -may be necessary to lock thevcatch plates in theiropen positions soas not to interlock with the shoulders on the spear.

Another object of my present invention is to provide means whereby thesame roller may be operated'either from the bottom or top of the window.

Other objects and uses will be brought out in thefollowing description.I

In the dra'wingsFigure 1 is an enlarged longitudinal sectional view ofa'portion of a curtain roller embodying the various features of myinvention. Fig. 2 is an outer end face view of the detached catchcarrying disk and catch plates thereon, showing the catch plates aslocked in their open positions] tional view of the same disk taken online Fig. 3 is a transverse vertical sec-' 33, Fig. 2. Fig. 4 is anouter end face view of the detached catch carrying disk, the catchplates being removed to show the spring thereto. Fig. 5 is an inner endface view of the same disk showing the adjacent portion of the springattached thereto. Fig. 6 is a plan of the blank for forming the catchcarrying disk. Fig. 7 is an enlarged sectional view of the catchcarrying plate through the channels as developed in a straight line.

In illustrating my invention I have shown 90 manner of connecting theadj acent end of the a "portion of a roller 1 having a central circularchamber 2 extending some distance inwardly from one end for receiving aspindle 3. This spindle is also provided with a central lengthwisesocket 4 opening from one end in which is tightly driven the reduced endof a spear -5 having a series of radially projecting fins to firmly lockthe spear and spindle to each other against relative rotation. The outerend of the spear extends some distance be yond the adjacent end of thespindle --3 and is provided with a flattened portion for engagement witha suitable bracket not shown to hold the spindle 3 against rotation. Theintermediate portion of the spear 5 between the flattened end 7 andadjacent end of the spindle 3 is preferably circular and of greaterdiameter than the portion which enters said spindle and is provided witha plurality of, in this instance two, grooves 8 and a circular bearing9-' just at the inner end of the grooves, said grooves forming shouldersadapted to be engaged by a corresponding number of radially movablecatch plates .10 presently described.

Acne-piece catch carrying disk 11 shown in its developed form in Fig. 6is adapted to be secured to the spear end of the roller.1 to form abearing for said roller upon the journal 9 of the spear and is alsoprovided with means for interlocking engagement with the adjacent end ofacoiled spring 12 and in addition to these functions is provided withmeans for receiving and retaining the catch plates .10 in operativeposition. For these purposes the central portion of the disk is pressedlaterally beyond the plane of the main body to form a circular hub 13journaled upon the bearing 9, while the margin of the disk is providedwith a plural-ityof, in this instance four, lugs or ears 14 preferablyarranged at the four corners of a rectangle and deflected or bentlaterally in the same direction as the hub 13 for entering correspondingrecesses or grooves in the periphery of the adjacent end of the roller 2to lock the disk and roller against relative rotation and at the sametime 'holdin this end of the roller concentric with the axis of thespindle 3 and spear Two of the diametrically opposite sides of the disk11- are provided with similarly formed wings or flanges 15 Which arebent at substantially right angles to the main body in a directionopposite to that of thehub 13' and lugs .14 and the outer edge of eachflange or wing is pro Vided with a plurality of,,in this instance three,tongues IGQ, preferably spaced equi-distant apart and bent inwardlytowardthe axis but apart from themain body of the disk so as to formintervening guide grooves for the reception of the adjacent edges of thecatch plates l0. The remaining diametrically opposite sides of the disk-11 are provided with laterally projecting wings or flanges 17 which arebent outwardly at right angles to the main body of the disk or in thesame direction as the flanges -15- to form suitable stops for limitingthe outward sliding movement of the catch plates 10. These catch platesare somewhat similar to those in my pending application referred to andconsist of similar flat sheet metal sections mounted upon the disk -1lin the manner described at opposite sides of the spear in the transverseplane of the grooves 8 and are provided on their inner edges withshoulders 18- reversely arranged for engagement with said grooves in theusual manner when used in connection with an overhead curtain roll. Onthe other hand when it is desired to position the curtain roll at thebottom of the window, the operation of these catch plates is undesirableand in order that they may be held in their open positions, the centraltongues -16 may be bent inwardly between the meeting edges of the plateswhen in their open positions as shown in Figs. 2 and 3, thereby allowingthe curtain to be raised and lowered and held in position by the usualmeans employed for curtains which are drawn from the bottom upward.

By making the disk 11 of bendable metal, the central tongues -l6 may bereadily bent inwardly or outwardly as may be desired according. to thelocation of the curtain either at the bottom or top of the window. Aspreviously stated this disk -1l also forms a convenient anchorage forthe adjacent end of the coiled spring and in order that the attachinghelix of said spring may be held against relative tilting movement ofthe disk, portions of the latter at opposite sides of the center aredepressed to one side of the plane of the main body to form raisedquarter circular ribs 20 on one side of the disk and correspondingchannels or grooves 21 in the opposite side of the disk, said groovesterminating in apertures -22 through said disk for permitting theadjacent helix of the coiled spring to be readily inserted through thechannels 21 as shown more clearly in Figs. 4 and 5. That is, theapertures 22 define the ends of the channels which are formed bypressing the intervening portions of the disk to one side of the planeof the main body thus leaving a bridge -2 between the adjacent ends ofthe channels, such bridge being in the plane of the main body. It is nowclear that the channels engage one side of the helix of the springpassed therethrough, while the bridge engages the opposite side of saidhelix and prevents relative tilting of this portion of the spring whenthe latter is under tension.

The catch carrying disk 11- is additionally held upon the adjacent endof the roller 1 by means of a ferrule 25 which is tightly fitted uponthe periphery of said roller and has its outer end overhanging andpreferably engaged with the flanges 15- and 17, thereby forming a shieldto protect the sliding plates in a measure against contact with externalobjects which might interfere with their free action and at the sametime the ferrule gives a certain degree of finish to the end of theroller and aids in positioning the curtain or shade upon said roller.The main features, however, of the invention consist in providing aone-piece catch carrying plate with means of attachment for one end ofthe coil spring, additional means for holding the spring against tiltingmovement relatively to the disk, and further means for retaining thecatch plates in operative position there on and for holding the cat-chplates when necessary against inwardmovement toward each other.
